so I have two questions. 1. I got this Alocasia about 1 month ago. Its quite healthy in its nursery pot and it put out a new leaf. at first I thought it was an amazonica but the more I look the pictures online it feels a little too green to be an Alocasia amazonica. Any idea what it could be? or is it just greener because its a juvenile plant?
2. it frequently has water droplets on the (at that time) newest leaf. I guess it is because of excess humidity as I live in Greece (natural 50-70% humidity without a humidifier) but just for safety's sake, humor me

It looks like it is a juvenile Alocasia 'Poly' to me from what I can see of your photo. Color can vary in juvenile leaves. The droplets you are seeing are a process called guttation. Aroids (and some other plants) possess glands called hydathodes that produce droplets of fluid when the plant's preferred air temperature is to low, or air movement around the plant is too still.

Your container looks a little too large for that plant. You should be very careful not to overwater.

Gina thanks a lot for replying! I'm having trouble believing the low temp possibility since we had an average fo 30 degrees Celsius. I'll try to encourage the air circulation. As for the container it is the original pot that I bought it in and I use a moisture meter to be safe.

That's great. Guttation can be triggered by both conditions or either. A lot of people see it on Philodendrons when they are grown indoors.
Just as an aside LOL the name 'amazonica' doesn't denote a species of Alocasia. Its not a valid name, but has been in use so long (since the 1950's) that it has become a common usage. The name originated in a nursery in Miami called the Amazon Nursery when the owner, a retired postal worker and plant enthusiast, found a plant among his stock that was clearly different from the others he had. He separated it out and decided to name it after his nursery, so he named it Amazonica.

Thats very interesting! The nurseries in greece barely label the plants they sell (they put the genus at most) so im trying to figure it out as I go. I am a bit cunfused and trying to figure out the humidity situation for winter because online i see everyone uses humidifiers but the mediteranean climate has really humid winters (more people use dehumidifiers than humidifiers including me when i was living on an island and the humidity was at 90%) but i am not sure how will that go with heating and closed windows at wintertime (sorry if i make any spelling error english is not my mother tungue)

I even saw a nursery labeling an adansonii as obliqua for 15 euro and....yeah sure

LOL yeah that would be cheap for an obliqua...I think the last one that sold at auction was like over $2000. A Variegated Adansonii just sold on eBay for over $3300.00. It was a record for that plant.

Yes the plant called ALocasia amazonica (or sometimes alocasia x Amazonica) is a hybrid ofAlocasia longiloba (reclassified from the name A. watsoniana) x Alocasia sanderiana. Both of these of course are species plants. The plant now commonly called Alocasia amazonica as though it is itself a species is a hybrid, that does not come from and has never actually grown in nature in either the Amazon or the rainforest. That name was given to the hybrid by Mr. Salvadore Mauro, who at that time in the 1950's when the hybrid was found at his nursery, owned the Amazon Nursery in Miami.

Alocasia 'Poly' is a cultivar of the hybrid amazonica which is smaller and has a slightly different leaf space. It was originally called 'Poly' by Aroidist Bill Rotolant, who in his turn owned a different nursery where the 'Poly' was discovered. They named it that because they thought it was a polyploid hybrid. The name 'Poly' somehow got turned into 'Polly' by the plant trade.

Your Alocasia will do fine in low humidity as long as proper soil moisture is maintained. In dry air, the soil tends to dry out sooner and that can cause problems including spider mites. No need to use a humidifier or to mist it. Just pay close attention to the watering.

Hello! I just recently received an Alocasia for my birthday; I believe that it is Amazonica. When I received it, there were already some holes in the leaves. I took it home and kept it in its nursery pot. It's been three days since I had it, and one of the leaves is starting to yellow and droop. I live in the midwest so the humidity is very low and I was wondering if I needed to add moisture into the air. Also, referring back to the holes in the leaves, Some of the holes are getting larger, or the leaves are becoming spongy (?) in certain areas. I have it in indirect light and the soil is moist. I'm afraid that I am killing this plant. This is my first time branching off into tropical plants and I want to make sure that I keep it healthy and happy. I can upload a picture of it later if needed.

Thank you for everything!

Alocasias are not easy indoor plants because they are very unforgiving of even minor watering lapses.

The holes were there before you got it so there is no way to determine the cause. They will probably continue to spread and the isn't much you can do about that.

Some lower leaf loss is normal, especially after it has been relocated. Lots of very bright but indirect light will help. So will keeping it in its nursery pot.

Monitor the soil moisture very carefully. It will need a thorough watering as soon as the surface of the soil is almost dry. Look for it to turn a slightly lighter shade of brown. As long as you water it properly, the humidity will not be an issue. You can expect it to lose as many older leaves as it gains newer ones.

Photos are always helpful and might reveal something you didn't think to mention.

Thanks for the photos. It does look like it suffered some abuse before you got it. The discolored leaves can be trimmed off. Make sure it stays warm, gets good ligh,t and water it as I described.

I'm not sure I've ever seen that before. It could be a nutrient deficiency, or a virus
